This repository is the source code that accompanies a course on Udemy.com that teaches students how blockchain technology works by coding out their own blockchain prototype in javascript.

The course is called Learn Blockchain By Building Your Own In JavaScript and it can be found here.

The first step in running this project is to run npm install.

The rest of the steps can be found in the course!

In this course you will build out your very own blockchain and decentralized blockchain network using the javascript programming language.

In this course you will learn all of the following concepts and your blockchain will have all of the following features:

• A proof of work algorithm to secure the network.
• Hashing algorithms to secure the data within the blockchain.
• The ability to mine (create) new blocks that contain data.
• The ability to create transactions and store them in blocks.
• An API/server that will be used to interact with the blockchain from the internet.
• It will be hosted on a decentralized blockchain network.
• A consensus algorithms to verify that the network nodes have valid data and are synchronized.
• A broadcasting system to keep the data in the blockchain network synchronized.
• Many other awesome features!...

When you have completed this course you will have built out your own blockchain prototype in code. You will have a thorough understanding of how blockchain technology actually works and why this technology is so secure and valuable. You will also have a deep understanding of how decentralized blockchain networks function and why decentralization is such an important feature for securing the blockchain. The whole process of storing, securing, and validating data/transactions on the blockchain will become very clear.
